Just got a 2015 MDX Base model, white diamond pearl. Looks and runs great so far. Wife and I are disappointed with sound of stock stereo. Seems very tinny and not very warm sounding. Have played with the settings for the sub, bass and treble but doesn't seem to help much. I heard there might be a way to get into the development mode and change the DSP settings to help it. I have seen posts about how to get into those menus for a MDX with the tech/nav package but not for a base model. Does anyone know? Thanks in advance.
